Morbidity and Mortality Weekly Report Notes from the Field Public Health Response to a Human outbreak. A World Health Organization (WHO) standardized Immunodeficiency Virus Outbreak Associated injection practices assessment tool (6) was used to interview with Unsafe Injection Practices — Roka licensed health care workers, including physicians, nurses, and Commune, Cambodia, 2016 laboratory technicians, and observe all injections administered.

Cambodians receive 0.8–5.9 therapeutic injections per A total of 115 injection events were observed, and 39 health person per year, one of the highest reported rates worldwide care workers were interviewed (Table); 99% of injections were (1,2). Appropriate medical injections and infusions can be administered with needles and syringes taken from unopened, health sustaining or lifesaving; however, improper adminis- sterile packs.

In 2000, it was estimated cedures did not precede injection in 79% of events, and a new that worldwide, unsafe injection and waste disposal practices cotton swab was used in only 36% of events. Observation of account for 260,000 new human immunodeficiency virus safety practices demonstrated that 63% of health care workers (HIV) infections annually (3). recapped needles after use; 51% were recapped with two hands.

All 39 interviewed health care workers unsafe medical injection practices by an unlicensed health care knew that HIV could be transmitted through unsafe injection practitioner as the likely source of the outbreak, highlighting practices, but fewer were aware of the potential for transmis- the potential for unsafe therapeutic injection practices to con- sion of hepatitis B virus (79%) and hepatitis C virus (62%) tribute to HIV transmission in Cambodia. After this outbreak, through this route. Finally, 28% of health care workers reported the government of Cambodia implemented new regulations ever experiencing a needle stick injury, and 49% reported ever to prohibit unlicensed medical practices (5). Although the receiving formal injection safety training. outbreak was associated with the unregulated health sector, it Although this study found little reuse of injection equipment prompted an assessment of injection safety practices among and high knowledge of the risks of unsafe injection practices licensed health care workers in Cambodia, given the high public related to HIV transmission, none of the observed injections demand for medical injections. To identify potential gaps in safe fully adhered to WHO standards of practice, thus potentially injection practices, the Cambodia Ministry of Health (MOH) compromising both patient and health care worker safety. To partnered with CDC and the medical technology company address these gaps, an intensive training curriculum on safe Becton Dickinson (Franklin Lakes, New Jersey) to conduct a injection practices for health care workers is being developed rapid assessment of injection practices at public health facilities. by Becton Dickinson with technical support from CDC. After From September 26–29, 2016, a team of medical officers review and approval by the Cambodia MOH, expert master from CDC and a clinical team from Becton Dickinson with trainers will administer this training in the same health care expertise in infection control assisted the Cambodia MOH facilities where the baseline assessment was conducted.
